Optical Coating
Electromagnetic Blocking
It is an electromagnetic barrier vacuum thin film technology for military warring devices based on electromagnetic radiation emission (RE102) by specification MIL-STD-461E. The frequency cut-off range is 2 to 18,000MHz and up to 2.5GHz.
Principle
It is a vacuum thin film deposition technology that blocks electromagnetic waves by repeatedly coating the product with high refractive chemicals and low refractive chemicals using vacuum thin film deposition.
